Parody (loosely) of Superman vs. The Amazing Spider-Man. And that's a guess; the similarities are strong but hardly definite. Supporting the notion, though, is the thematic similarity: like Marvel Zombies vs. Army of Darkness, a collaboration between Marvel Comics and Dynamite Comics, Superman vs. Spider-Man was also an inter-company crossover, the first between Marvel and DC, in fact. In this case, Ash bears a more-than-passing resemblance to the Man of Steel. What the hell Wolverine is doing there, I don't know.
